Application filed riovemher 27, 1914. Serial No. 874,326.

To all whom it may concern:

Be it known that I, CARL RAsnUssEN, engineer, a subject of the King of Norway, residing at Brunswick, Germany, have invented certain new and useful Improvements in (.alculating-Machines, df which the following is a specification.

My invention relates to improvements in calculating machines, and. more particularly in calculating machines of the glass in which the carrying mechanism consists of rockers cooperating one with each of the numeral wheels of the registering mechanism (except the one of the highest order), which rockers are adapted to set the mechanisms for transmitting the values to the numeral wheels of the higher orders in such a way that the said numeral wheels are shifted a distance corresponding to one value, which rockers are operated by the numeral wheels when passing from the nine position to the zero position, or vice versa. The objectof the inun'ovements is to provide novel locking means for holding the said rockers in operative positions until the carrying oporation has been completed, which locking means are simultaneously thrown in nonlocking positions by the mechamsm for transmitting the values to the numeral wheels.

l or the. purpose of explaining the invention l shall describe hereinafter a calculating machine of the class in which setting disks are provided for setting andv transmitting the registering mechanism upon rotation by a machine crank. A machine of this class is shown and described in the Patent of the l nited States No. 1,100,689 granted to me. June 10. 1914. But l wish it to be understood, that my invention is not limited to the embodiment in a machine of the type shown in the said patent.

ln the drawing Figure 1, is a vertical cross-section of the registering and carry-- ing mechanism of the calculating machin Fig. 2. is a partial plan view of the machine with the cover of the casing removed. and Fig. 3, is a side view showing a detail o the machine illustrated in Figs. 1 and .3.

lzleferring to the example illustrated in the. drawing, the. registering mechanism mmprises intermediate gear wheels a adapted to be operated from the setting mecha nism upon rotation thereof by the machine crank. .'\s the setting mechanism does not values to the numeral wheels of the form a part of my invention I have not illustrated the same in the figures. In the op eration of the machine the intermediate gear wheels are rotated through arcs which correspond to the numbers set on the setting disks, and such rotation is transmitted from the intermediate gear wheels to cooperating numeral wheels 7r: through the intermediary of gear wheels 1: connected one with each of the numeral wheels. 1

The numeral wheels 71: or the gear wheels 71: are each provided with a nose 0 which is adapted to rock a member lb having a rocking support on a relatively fixed shaft 2', and the noses 70 are disposed in such positions, that the rocking movement is imparted to the members It whenever the numeral wheels pass from their nine positions to their zero positions, or vice versa. An arm k of the rocker carries a block 9 which is formed with two cam faces arranged on opposite sides of the block. The block 9 is located at the side of a disk which is provided with a. radially shiftable tooth c (or where the setting mechanism is adapted to be rotated in both directions with two teeth one for multiplication and the other one for division). The tooth e is located in such a position that when shifted into,operative position it engages in the teeth hf the intermediate gear wheel a of the'next higher order. For shifting the tooth it is formed with a lateral nose 0 which is located in the path of the block and adapted to ride on the cam face thereof. The disk f is operatively connected with the machine crank or a part connected therewith, so that it takes part in the rotation of the same and the set-- ting mechanism, and when it is rotated with the tooth c in operative position the intermediate gear wheel a of the next higher order is rotated through an angle corresponding to one value.

The rocker h, 71. must he held in operative position, until the tooth 6 has passed and performed the carrying operation. F or this purpose it is provided with an arm 7L2 which is adapted to he engaged by a spring (Z when the rocker h is rocked, so that the latter can not return into normal or inoperative position.

In order that all the rockers h, it can simultaneously he returned into operative positions, the springs (Z are secured to a rock shaft m which is held by a spring 7) with the springs J in looking positions, and which is adapted to he rocked with the springs d away from the rockers ii, k so that all the rockers are released and drop into their normal or inoperative positions shown in Fig. 1. Automatic means are provided for rocking the shaft m with the springs (Z out of locking-z engagement with the. rockers As shoun the shaft c is provided. with a earn a which is adapted to engage a lever m" secured to the shaft m so as to rock the latter with the signings at out of locking engage,- ment with the rockers 7t, 71,.

I olaim herein as my invention:

In a calculating machine, the combination with the numeral wheels, and mechanism for transmitting values thereto, of rockers located in positions for being rocked by said numeral Wheels, means controlled by said rockers for carrying a value to the numeral wheels of higher order. spring locks one for each 01 the rockers and adapted to lock the rockers in rocked positions, a rock shaft carrying all of said spring looks, and means controlled by said transmitting mechanism for rockin said rock shaft with the spring looks out of locking positions.

In testimony whereof have hereunto set my hancl in presence of two'subscribing witnesses.
